Buying versus leasing

You have to think about you are not beatable… e.g. I have a Boeing 737-700 HGW (winglets) which flies a 2,000km turn with 56% margin on 100% prices and same route a Boeing 737-800 HGW (winglets) which is leased just does 29%. If someone wanna beat me with a leased plane what should he take? A Boeing 737-700 BGW? This plane can also don’t resist my bought 73W. A Dash 8-Q400A (most profitable plane in whole game) can’t beat the 73W when it’s bought, too… You shouldn’t lose the view on a business which has future. I had once around 280M AS$ earnings but 100M AS$ were just leasing costs! With bought planes it would be maybe 5M AS$… all costs which you don’t have with leased planes…
